To all whom it may concern:

Be it known that we, JAMES F. OREBAUGII and OnARLEs W. CoNNE'rT, citizens of the United States, residing at Madison, in the county of Jefferson and State of Indiana, have invented new and useful Improvements in Gasolcne Turbine-Motors, of which the following is a specification.

This invention relates to gasolenc turbine motors, and one of the principal objects of the same is to provide a motor of the turbine type to be actuated by successive charges of hydro-carbon gas.

Another obj ect-of the invention is to overcome some of the defects of the crank-shaft type of motors by increasing the leverage of the character referred to without decreasing the efiioiency of the same.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal vertical section of a motor made in accordance with our inplurality of rotors of modified form.

vention. Fig. 2 is a front to rear longitudinal section of the same. Fig. 3 is a vertical section on the line'33, Fig. 2, looking in the direction indicated by the arrows. Fig. 4 is a plan view of one of the rotors. Fig. 5 is a sectional view of two of the rotors connected to a broken away portion of the shaft.

Fig. 6 is a sectional view of a portion of a Fig. 7' is a detail'side elevation of one of the rotors shown in Fig. 6. Fig. 8 is a detail sectional view of the same. I

Referring to the drawings for a more specific description of our invention, the numeral 1 desi ates a casing having at one end an exten ed reduced portion 2 provided with an exhaust port 3. The opposite end of the easing is provided with an opening 4, and, covering said opening upon the inside of the casing is a wire gauze screen 5. A central shaft 6 extends through the casing and is journaled in bearings 7 provided with screw caps 8, said bearings and cap having raceways provided therein for the balls 9, thus providing ball bearings at opposite ends of the casing. A fan 10 is secured to the shaft 6 adjacent to 0 the screen 5 for drawing air through the opening 4 and projecting it through the interior of l the casing to keep the parts cool. A. fan 11 I is secured to the shaft 6 in the exhaust chamber for driving the exhaust out through the 5 port 3. A partition 12 is fixed in the casin said partition having an aperture throug which the shaft6 extends, and secured to this partition is a series of explosion chambers 13, three of said chambers being shown in the drawing, but itwill be understood that any suitable number may be utilized. The explosion chambers 13 each consists of a tube open at its opposite end and provided with a series of cooling flanges 14 upon theouter sides thereof, the bore of the tube being en larged at one end. An inlet pipe for thefuel extends through oneend of the casing, said pipe 15 having branches 16 fitted in threaded inlet ports 17 disposed centrally to the explosion chambers. Fitted in the smaller ends of the explosion chambers are the plungers 18 for compressing the gas, said plungers being provided with suitable packing rings 19. The plungers 18 at their outer ends are provided with a cross pin 20 and engaging said cross pin is a lever 21 having a slotted end 22, said levers each being pivotally connected to aboss 23 extending outward from the partition 12, a bolt 24 extending through the lever 21 and into the boss 23, suitable washers 25 being disposed upon opposite sides of said lever. Each of the levers 21 is provided with an offset 26, and on the free end of the lever is a roller 27 which engages a cam roove 28 in a cam 29 keyed to the shaft 6. n the enlarged end of the explosion chamber is fitted a spring seated piston head 30, the end of which is beveled, as at 31, to fit the beveled seat in the explosion chamber. The stem 31 of the piston 30 extends throu h a cap 32 fitted to the outer end of the exp osion chamber, and a spring 33 encircles the stem and bears at one end against the'head 30 and at the opposite end against the cap 32.' The stem 31 extends into a buffer 34 bolted at 35 to the partition 12, and abolt 36 extends through the buffer 34, and is connected to the flanges 14, said bolt 36 being provided with a nut 37 which bears against the buffer 110 usual or any suitable type communicate with the ex losion chambers, as shown in Fig. 3,

said p ugs extending through openings 39 in the casing 1; An air inlet valve 40 seated by a spring 41 is provided with a roller 42 connected to the stem of the valve, said rollerengaging a groove 43 in the periphery of the cam 29 to admit air to the explosion chambers to be mixed with the gas prior to the sparking operation,

The rotors each consists of a hub 44 keyed to the shaft 6, and a series of spokes 45 extendin from the hub and rovided with an integra rim 46. A series 0 vanes or buckets 47 having concave upper surfaces and convex lower surfaces, are secured to the rim 46.

at their inner ends, and their outer ends are secured to an outer ring or annulus 48. Between each pair ofthe rotors is a stationary flange 49 through which a bolt 50 passes, said bolt extending through spacing sleeves 51 intermediate the flanges 49 an said bolt ex tendingTthrough an aperture in the partition 12 and provided with a nut 52 for securing thefia esrigidly thereto. At the inner ends of the an es 49 concave buckets 53 are provided, said buckets-being set oppositely to the vanes or buckets 47 of the rotors. An inclined inlet opening 54 extends through the wall of the explosion chamber and through the partition 12 said inlet opening commumeating with the en'largpd portion of the ex losion chamber and t e opposite end of said inlet ope being disposed at an angle to the concave uckets 47 so that the impact of the charge will give a rotary impulse to the rotor ad acent to the partition 12, while the expansive force of the charge will be utilized by the succession of rotors until the same reaches the "exhaust chamber. As. shown in Figs. 6, 7 and 8, the rotors each consists of a hub 55, s okes 56 and an in-.

tegral rim 57 provided wit apertures 58 having inclined walls 59, and secured between each pair of rotors is a fixed abutment .wheel 60 having a series of aperture s-61, the walls of which are plain, as at 62, said apertures communicating with the inclined apertures 58 in the rotors.

The casing 1 may be made in sections-and may be secured together by means of the flanges 63 and the bolts 64. Y a

T e operation of our invention may be briefly described as follows: The charge'of fuel being admitted at theroper time to the explosion chamber and air eing admitted by the unseating of valve 40,the plunger 18 1s moved forward to compress the charge and when it'is ignited its expansive force pushes the piston head 30 outward against the tenfor reciprocating t sion of the spring 33 until said head 30 passes beyond the inlet port 54, the plunger 18 still continuing in its movement to force the last atom of the charge through the ort 54 against the concave buckets 47 oft e rotor adjacent to the partition12. 'The charge is then transmitted from the buckets 47 through the openings in the stationary flanges to. the next rotor, and so on until the charge reaches the exhaust chamber and is driven out through-the port 3 by the fan 11. To start the motor we may provide a compressed air tank for giving the initial. start to the rotors, or lieu of this arrangement, we

ma merely utilize a crank for starting. 7

rom the foregoing it willbe obvious that a motor made in accordance with our invention is simple in construction, is compact, is light in Wei ht, is accumulative in action, utilizes all file explosive gases, and is kept cool by the fans, while the explosion chambers are kept clean owing to the action of the plungers 18 and the s ring pistons-3O.

a partition secured to said casing, a series of explosion chambers fixed to said casing, compressin plungers mounted to reciprocate in the exp osion chambers, a spring seated piston head mounted in the explosion chambers,
